A sinkhole under Curtis Road will keep it closed indefinitely, said Scott Merillat, Lenawee County Road Commission managing director, on Friday.

The road was closed Wednesday night when a hole developed in the pavement where the ground had begun settling several days earlier. It first has to be determined where water is coming from that caused the problem, he said.

“Yesterday was a poor day to see where water was coming from because it was coming from everywhere,” Merillat said. Rain and melting snow created localized flooding on county roads that crews have been dealing with, he said. On Friday, drivers were busy sanding and scraping ice that coated gravel roads and caused school closures.

Merillat said he hoped workers would be available next week to begin repairs on Curtis Road.

High water did not force the closure of any other county roads, he said. Standing water remains a hazard where snow has blocked it from draining off road surfaces, he said.
